Method and device for sending and receiving game content including download thereof

ABSTRACT

The present invention generally relates to methods and devices as well as handheld stations and computer program products for sending video game content to handheld mobile terminals, comprising broadcasting common video game content to handheld mobile communication terminals via a digital video broadcast handheld channel, to enable said handheld mobile terminals to execute video game applications.

The present invention relates to the field of game data transfer to handheld mobile communication terminals. The present invention also relates to mobile multi-player online gaming. During such games data including game content has to be sent from the server to the players and back. The present invention also pertains to the delivery of amounts of data to mobile terminal devices. The present invention also proposes a new way to deliver video game resources (application, sounds, game levels, graphics, etc.) over digital television broadcasts, wherein the video game can be tied with television content such as certain shows.

In the area of online gaming often, the same data has to be sent to a large number of players. Frequently, this data is not especially timing critical, e.g. new backgrounds, new levels, sounds or features or the game software itself. In online gaming there are also individual data that are often timing critical such as game character actions. The present invention strives to find a new way to optimize the use of data transfer resources for an optimal gaming experience.

This invention is also related to the networking solutions for high-quality mobile massive multi-player on-line games (MMOG). The present invention is especially related to a novel algorithm with an effective combination of UMTS and radio digital broadcasting system for handheld devices.

The global spread of on-line multi-player gaming has made it more important to investigate the network behavior and game performance for better and broader networking supports. With increased requirements of the players and the expanded scale of the games, the downlink traffic tends to occupy more and more bandwidth resource, which is scarce and expensive in mobile networks.

Today, applications, such as games, can be downloaded into consumer devices over the air (OTA) utilizing cellular networks, WLAN, BT, etc. These downloading methods offer different bit rates and have different radio frequency coverage ranges. While cellular networks today offer good coverage, the available bit rates do not allow large game content to be downloaded within acceptable time periods.

The term computer game is a game usually composed of a computer controlled virtual environment in which players may interact in order to achieve a goal or a set of goals. The expression “video game” is used in the text in the sense of a game that for execution is depicted on a screen or a display of a handheld terminal device. The expression “video games” is not used in the sense of a video console game that is strongly tied to a single hardware equipment. The term “video game” is used in the sense of computer game where the video display is the primary feedback or output device. The expressions “computer game” or “video game” are not restricted to games to be executed on personal computers or video game consoles. In the following text the expression video game is used to refer to interactive game software of computer and video games irrespective on which kind of device or terminal (neither personal computer nor video game console) it is executed.

According to a first aspect of the present invention a method of sending video game contents to handheld mobile communication terminals is provided. The method comprises broadcasting common video game content to handheld mobile communication terminals via a digital video broadcast handheld channel. This basic embodiment simply discloses the use of a digital video broadcast handheld channel for downloading common video game content.

This embodiment is directed to special game online games such as obstacle race (a game where a user has to avoid obstacles on a path with increasing speed) or other pure reaction games that are based on single data stream. This first example embodiment can be used to utilize the whole digital video broadcast handheld channel only for common video game content. The term “common video game content” has been selected to indicate that the video game content is common i.e. not individually tailored for each user or receiver. This first embodiment does not require any upload or uplink data transfer and may be used as a kind of downlink only game. It may also serve to download complete software updates.

This embodiment of the method is intended to be executed on a digital video broadcast handheld (DVB-H) broadcast station, especially for game content downloading. However, it is also possible to execute this method also at an online game server that is capable of digital video broadcast handheld (DVB-H) broadcasting including game content.

The use of mobile, digital TV broadcasting networks, provides a wide area coverage and high bit rate, to download large game content over the air for mobile online multi-player gaming.

It should be noted that a whole DVB-H channel may be used for data transmission alternatively to TV transmission (e.g. at times of the day when there is no TV program). It is also envisaged to utilize unused capacity of TV transmission (e.g. when the picture doesn't change much and the data stream for TV only requires a low data rate) for the data transmission.

In an example embodiment the method further comprises receiving said common video game content from a remote game server. In this case the sender or provider of the said common video game content may be a remote server, such as e.g. from an online game provider or from an advertisement server.

In another example embodiment the method can further comprise combining/integrating said common video game content (that may have been received from a remote game server) with/into a video data stream, and broadcasting said common video game content combined with/integrated in said video data stream to said handheld mobile communication terminal via a DVB-H channel including game content.

In yet another example embodiment the method further comprises receiving a video data stream, generating said common video game content according to a content of said received video data stream, combining said generated common video game content with said received video data stream, and broadcasting said common video game content combined with said video data stream to handheld mobile communication terminals via a digital video broadcast handheld channel.

The video data stream can be received from a digitizer, a storage, an archive, or a video stream provider. The common video game content is generated according to a content of said received video data stream. The software for generating said common video game content might be received from a remote game server. That is the common video game content is related to the video data stream. It is for example possible to define certain target areas in the video stream as common video game content. This embodiment is directed to provide a kind of augmented TV online gaming.

Then the generated common video game content and the video data stream are merged and broadcasted to handheld mobile communication terminals via a digital video broadcast handheld channel. That is the video game content is tied to the content of the video stream and may further be related to the content of the video stream.

In another example embodiment said common video game content is transferred to said handheld mobile communication terminals using Internet protocol datacast (IPDC).

In the context of massive multi-player games that are played by wide audiences who all share a lot of common data of the game world, such data could be sent in a broadcast, from which each client filters out the unnecessary data, using only the parts essential for the particular player.

The method of the invention may be extended by an additional step of filtering out the necessary data, using only the parts essential for that particular player for executing the online game application.

According to another aspect of the invention a method is provided for receiving video game content at a handheld mobile communication terminal. The method comprises receiving a common video game content at a handheld mobile communication terminal via a digital video broadcast channel, and using at least a part of said common video game content for executing a video game application on said handheld mobile communication terminal.

This basic embodiment may be embodied as the download of video game content at a handheld mobile communication terminal. This may be embodied to utilize the whole digital video broadcast handheld channel only for common video game content. The common video game content is common i.e. not individually tailored for each single terminal. This first embodiment does not require any upload or uplink data transfer and may be used as a kind of downlink only game.

In another example embodiment said method further comprises executing at least a part of said received common video game content. This embodiment requires an execution of the game application. This embodiment may also select a certain part of the common video game content for executing the video game application. This embodiment may not necessarily require an uplink. This embodiment may be used to transfer e.g. two different common video game contents to enable a two player combat game experience, with two different kinds of target areas that are e.g. only valid for a single user.

In yet another example embodiment of the present invention said common video game content is received at the handheld mobile communication terminal combined with a video stream of a digital video broadcast channel. In this case the method further comprises extracting said common video game content, from said video stream, and using at least a part of said extracted common video game content for executing a video game application on said handheld mobile communication terminal.

This embodiment discloses the use of a background download of common video game content via DVB-H, e.g. while a user is watching TV on his mobile device.

In another example embodiment of the invention the method further comprises displaying said received extracted video stream on a display of said handheld mobile communication terminal, and executing said video game application in the handheld mobile communication terminal in accordance with said received and displayed video stream.

This embodiment represents a kind of augmented television gaming, wherein the game is related to the content of a DVB-H audio or video stream.

This may be implemented as a “censorship” game, one-button game to “beep out” any mentioning of a name of a certain person in a TV play (with points for every completely garbled name (or other word such as “and”) and “negative points for garbled non-target words).

Another implementation could be a “play along music videos” implementation. In this implementation, a set of sample files is transferred in the beginning as part of the broadcast. The idea in the game is that the player must press correct buttons at correct times in accordance to audio signals (or respective display elements). The buttons the player should press may appear on the screen superimposed on top of the music videos, or may each be illuminated at the point in time these keys have to be pressed. It is also possible that the buttons trigger musical sample files that are in harmony with the part of the music that is currently heard. In addition to “jamming” along the music video, also a score is calculated about the player's efforts.

It may also be possible to use special audio/video games that require to press a certain button in case a certain character or a certain event occurs in the video stream, for example to generate a certain sound effect as an confirmation.

In yet another additional example embodiment the method further comprises depicting said received video stream and video game display elements of said executed video game application superimposed on said display on said handheld mobile communication terminal.

This feature allows the implementation of games with a wide variability of forms such as “Assassin” wherein in the beginning of a television program, the player sees a picture of the character he must attempt to “shoot” during the television program. Every time the character appears on the screen, the game application is notified about this. This gem may also be extended by a crosshair that may be moved via screen to aim a virtual weapon to a certain character. In the end of the program, the game shows to the player how many “hits”, “misses” and “innocent victims” he made at shooting the character. This use case fits particularly well for cartoon television shows.

It may be considered to use similar games for broadcasts of sport events (for directing water bottles to a player), parliament broadcast debates (directing a microphone to a certain Member of Parliament) and the like. The same principle may be implemented as the game “anonymous” wherein a user controls the location, size and the orientation of a black eye bar on the display to anonymize e.g. a certain character in e.g. a TV series.

In yet another additional example embodiment the method further checks if said executed video game content is related to an actual content of said video stream displayed on a display of said handheld mobile communication terminal. In this embodiment the executing of said video game application can be interrupted (and the video game content may be deleted) if said executed video game application is not related to an actual content of said video stream displayed on a display of said handheld mobile communication terminal. That is, after a certain broadcast has ended, the resources become unusable. This may be implemented as a watch and game implementation, wherein it is only possible to execute a certain game when a DVB-H program is received. However in a more sophisticated embodiment the game may be terminated if a certain TV program or TV has ended.

It is for example possible to implement “playable commercials”, i.e. special advertisements during which small games could be played. The theme of the game could be closely related to the advertised product: e.g. a kind of “Snakes” game in a commercial for a candy coated chocolate pastilles wherein the snake hunts graphic elements in the form of candy coated chocolate pastilles.

In another example embodiment of the present invention the common video game content is related to the multi-player online video game application. In this embodiment the method further comprises sending individual video game content via a wireless wide area communication network. The individual video game content is exchanged with a game server or with another player for executing a multi-player online game. The term “individual video game content” has been selected as a content that is terminal specific and may be timing critical. The individual video game content may be transferred from a terminal device to a game server and may comprise e.g. position and status data of a player in a virtual environment and game input data which may be transferred to, e.g., an online game server. The individual video game content may be transferred via an online connection via a telecommunication network such as a cellular telephone network. It is also envisaged to transfer individual video game content from a server to a terminal via an online communication connection such as e.g. scores timing critical updates and the like. In the context of the present invention individual video game content is transferred via a mobile communication network and the common video game content is sent by using DVB-H broadcast.

Such a multi-player online game may be implemented as “Play the commercial”. This implementation is an application to other television content besides programs. This embodiment may be implemented by the task to press a button when a certain commercial is shown. When the player has caught e.g. 50 chocolate bar commercials, he may be rewarded with a free box of these Products. The advertisers also benefit from these types of games because they can get data about the visibility of their advertisements.

In yet another example embodiment of the present invention the method further comprises receiving individual video game content from a game server or from another player via a wireless wide area communication network.

This embodiment may be implemented for example as a betting service on events occurring in live broadcasts. In the beginning of the broadcast of some live event (e.g. an ice hockey game, a horse/car race, or the like), the game application is transferred to the terminals. The users can place bets in real-time of e.g. who they guess is going to be the next player getting a penalty, scoring a goal, etc. that are then transferred as individual game content to another player, an online betting-office or an online bookmaker. Depending on the legislation of the country where this service is provided, the player could actually bet real money from his account. This implementation can be used to transform, everyday television watching (except of repetitions of TV shows) into a game.

According to another example embodiment said wireless wide area communication network is a wireless wide area communication network according to the universal mobile telecommunication system standard. This implementation is directed to DVB-H enabled cellular game phones or cellular smart phones.

In another example embodiment of the present invention said common video game content is received at a handheld mobile communication terminal via a digital video broadcast channel using Internet protocol datacast.

According to another aspect of the present invention a method for exchanging video game content of an online video game on an online video game server with a number of connected handheld mobile communication terminals is provided. The method comprises operating an online video game on said online video game server, sending common video game content to at least one handheld mobile communication terminal via a digital video broadcast channel, and receiving individual video game content from at least one connected handheld mobile communication terminal via a wide area communication network.

The operation of an online video game application on said online video game server comprises executing at least a part of said video game content for managing, executing, or controlling a video game application. By performing these actions the online video game application can be executed at least partially on at least one (connected) handheld mobile communication terminal.

In an embodiment the game server simply provides common video game content via a digital video broadcast channel as a down-link and receives individual video game content from connected handheld mobile communication terminals via a wide area communication network as an uplink. This allows a complete data exchange between the game server and gaming terminals. This embodiment is especially suitable for games that use a common virtual game area.

In an example embodiment the method further comprises sending individual video game content to at least one connected handheld mobile communication terminal via a wide area communication network such as e.g. a GSM (Global System for Mobile communication) mobile telephone network. It is for example possible to use e.g. GPRS (general packet radio service) of GSM for downloading player specific information directly top a certain user.

In yet another example embodiment said wireless wide area communication network is a universal mobile telecommunication system, which is also known as UMTS. More exactly the wide area communication network is a wide area communication network that is operated according to the data formats protocols and standard of UMTS.

In another example embodiment the method further comprises receiving a video data stream, generating said common video game content according to the content of said received video data stream, sending said common video game content to a broadcast station for combination with a video data stream to handheld mobile communication terminals via a digital video broadcast handheld channel. The method further comprises checking if said received individual video game content is related to an actual content of said video stream, and interrupting the reception of said individual video game content if said received individual video game content is not related to an actual content of said video stream.

By receiving a video data stream, generating said common video game content according to the content of said received video data stream the game server can be used to provide an augmented reality TV online game experience to users of DVB-H enabled terminals.

A DVB-H transmitting station may perform the transmission of the common video game content on a video data stream in a DVB-H channel to handheld mobile communication terminals.

Up to this section the server serves as a game server for generating common video game content according to a video stream. However the game server also executes an online game that is performed/based on individual game data that are received or exchanged with connected mobile terminal devices. The online game server can execute the game in a timing critical manner and only as long as a respective video game content is executed.

This embodiment of the method is executed a the game server and further comprises checking if said received individual video game content is related to an actual content of said video stream, and interrupting the reception of said individual video game content (and maybe deleting said video game content) if said received individual video game content is not related to an actual content of said video stream. With these steps the game server ensures that after a broadcast has ended, the resources become unusable, as the game server rejects all incoming individual game content.

In still another example embodiment said method further comprises generating said video game content, checking if said video game content is timing critical, and classifying said video game content as common video game content if it is not timing critical and classifying said video game content as individual video game content if it is timing critical.
